LOL. Perhaps one should assume that the majority of IP space is
reserved for smptpd's. ;)
Trust me, I see your point. I thought the same when I first started,
and saw all the IP's being added. So I spent a /tremendous/ amount
of time just /sure/ I was going about it incorrectly. Turns out I
was wrong, and it was working better than I thought /it/ or /any/
anti-spam mechanism could. Turns out, after a year of closely
working with it, I can state with all confidence, that it is the
most effective system ever conceived. I'm not bragging here. I had
no conception when I started this, that it would/could be this
effective. But, surprisingly, it is. :)

Yes.

Not sure I completely follow you here. As to the "quarter of the IPv4 space"
Did you imagine that more than 3 quarters of the IPv4 space is in use by
legitimate mail services? Where will all the dynamic IP space come from
for all the ISP/providers?

Huh?
Look, I had already been up for 2 days straight when I wrote this -
I alluded to this fact in the beginning of the thread. So I'm afraid
I let my impatience leak out. I have had some rest since then, and
believe my replies will be more thoughtful, as they normally are. :)
Apologies to all for my being so short.

Best wisher.
